How to reconcile detached HEAD with master/origin

Approach1

If you find yourself in a detached HEAD state in Git and want to reconcile it with the master or origin branch, you can follow these steps:

• Check out the branch you want to reconcile with. For example, to reconcile with the master branch:

$ git checkout master

• Use the git merge command to merge the changes from the detached HEAD into the current branch. This command merges the changes from the detached HEAD into the master branch. Note that HEAD@{1} refers to the commit that was at the HEAD of the detached branch before you checked out the master branch.For example:

$ git merge HEAD@{1}

• Resolve any merge conflicts that may arise during the merge process. Git will automatically attempt to merge changes from the detached HEAD and the branch you are merging into, but if there are conflicting changes, you will need to resolve them manually.
• Once you have resolved any merge conflicts, use the git add command to stage the changes, and then use the git commit command to commit them. This command stages and commits the changes that were merged from the detached HEAD into the current branch.For example:

$ git add .
$ git commit -m "Merge changes from detached HEAD"

• Finally, push the changes to the remote repository to reconcile the changes there as well. For example, to push the changes to the master branch on the origin remote:This command pushes the changes in the local master branch to the master branch on the origin remote.

$ git push origin master

• By following these steps, you can reconcile changes in a detached HEAD with the master or origin branch in Git.

Approach2

Another approach to reconcile a detached HEAD with the master or origin branch is to create a new branch based on the detached HEAD, merge the changes from the new branch into the master or origin branch, and then delete the new branch. Here are the steps to follow:

• Identify the commit hash that corresponds to the last commit on the detached HEAD. You can do this by running the following command:This will show you the commit history for the repository, with each commit listed on a single line, along with its corresponding commit hash.

$ git log --oneline

• Create a new branch based on the detached HEAD by running the following command:Replace <commit-hash> with the hash of the last commit on the detached HEAD that you identified in step 1.

$ git checkout -b new-branch

• Merge the changes from the new branch into the master or origin branch by running the following command:This will merge the changes from the new branch into the master branch. If you want to merge the changes into the origin branch, you will need to push the changes to the remote repository after the merge.

$ git checkout master
$ git merge new-branch

• Delete the new branch by running the following command:

$ git branch -d new-branch

• This will delete the new branch that you created in step 2.

By following these steps, you can reconcile changes in a detached HEAD with the master or origin branch in Git.
